Journal ArticleDOI
Fano resonances in nanoscale structures
TL;DR: In this paper, the authors introduce the concept of Fano resonances, which can be reduced to the interaction of a discrete (localized) state with a continuum of propagation modes, and explain their geometrical and/or dynamical origin.

Nano-optics of surface plasmon polaritons
TL;DR: A surface plasmon polariton (SPP) is an electromagnetic excitation existing on the surface of a good metal, whose electromagnetic field decays exponentially with distance from the surface.

TL;DR: Two reduced-symmetry nanostructures probed via confocal spectroscopy, a dolmen-style slab arrangement and a ring/disk dimer, clearly exhibit the strong polarization and geometry dependence expected for this behavior at the individual nanostructure level, confirmed by full-field electrodynamic analysis of each structure.

Fano Resonances in Plasmonic Nanoclusters: Geometrical and Chemical Tunability
J. Britt Lassiter,Heidar Sobhani,Jonathan A. Fan,Janardan Kundu,Federico Capasso,Peter Nordlander,Naomi J. Halas +6 more
TL;DR: It is shown that clusters of plasmonic nanoparticles and nanostructures support Fano resonances, and that this spectral feature, produced by the interference between bright and dark modes of the nanoparticle cluster, is strongly dependent upon both geometry and local dielectric environment.
